Antisemitism (also spelled anti-Semitism) – prejudice, hatred of, or discrimination against Jews for reasons connected to their Jewish heritage – has experienced a long history of expression since the days of ancient civilizations, with most of it having originated in the Christian and pre-Christian civilizations of Europe. In the 20th century, antisemitism during the reign of fascist regimes such as Nazi Germany resulted in the death and dislocation of the majority of Europe's Jewish population.
